Procedural workflows have become a core part of modern visual effects production, allowing artists to create complex simulations, custom tools, and flexible systems instead of relying only on manual operations. In SideFX Houdini, VEX programming provides artists with deeper control over geometry, attributes, simulations, shaders, and procedural effects. However, learning VEX can be challenging because it requires understanding both programming concepts and Houdini’s unique procedural approach.

Rebelway – VEX for Houdini Artists 2024 is an advanced online VFX course focused on teaching artists how to use VEX programming inside Houdini to build custom effects and procedural workflows. According to the official course page, the training covers programming fundamentals, logic, algorithms, geometry manipulation, volumes, Vellum forces, procedural textures, clustering algorithms, motion design systems, and advanced VEX techniques used by professional FX artists. The course contains 30+ hours of training, runs for 8 weeks, and is designed for intermediate Houdini users.

Designed for Houdini FX artists, technical artists, TDs, and procedural workflow developers, the course helps artists move beyond standard node-based workflows and gain deeper control over Houdini systems through code.

What is VEX for Houdini Artists?

VEX for Houdini Artists is an online FX programming course from Rebelway focused entirely on writing and applying VEX code inside Houdini.

VEX (Vector Expression Language) is Houdini’s high-performance scripting language used for manipulating geometry, attributes, shaders, and simulations.

According to Rebelway, the course teaches artists how professional VFX artists use VEX to enhance their FX workflows and solve complex procedural problems.

The course covers:

VEX programming fundamentals
Houdini attributes
Geometry manipulation
Procedural modeling
Volume processing
Ray casting
Vellum simulations
Algorithms
Clustering systems
Motion design workflows
Karma and Solaris rendering

Learn VEX Programming Fundamentals

The course begins by establishing the programming foundation required for Houdini scripting.

Students learn:

Variables
Data types
Functions
Logic
Loops
Algorithms
Debugging techniques

According to the official curriculum, the early lessons explain why artists would use VEX instead of relying only on SOP workflows and how VEX interacts with Houdini internally.

This foundation allows artists to create more flexible procedural systems.

Geometry Manipulation Using VEX

One of the biggest advantages of VEX is direct control over geometry and attributes.

The course teaches artists how to access and manipulate:

Points
Primitives
Vertices
Groups
Attributes

Students learn how to create custom geometry behaviors and procedural effects that would be difficult or inefficient using standard nodes alone.

Visualizing Data with VEX

Understanding attributes is essential for advanced Houdini workflows.

The course explores how VEX can be used to visualize and control procedural data.

Topics include:

Attribute creation
Attribute modification
Geometry analysis
Custom visual effects
Ray casting techniques

Students also create a custom ambient occlusion shader using ray-based methods as part of the training.

Work with Volumes, Geometry, and Pixels

VEX is not limited to 3D geometry.

According to the course curriculum, students explore the 2D side of VEX by learning how images and pixels are represented inside Houdini.

Topics include:

Image processing
Sampling techniques
2D operations
Texture manipulation
Custom texture baking

The course includes creating a custom Mari-style texture baker using VEX-based workflows.

Create Custom Vellum Forces

VEX provides powerful control over Houdini simulations.

The course teaches students how to use VEX inside Vellum workflows to create custom forces and simulation behaviors.

Projects include:

Surface tension effects
Custom gravity systems
Procedural forces
Dynamic constraints

Artists learn how code can influence simulations over time and create unique behaviors.

Learn Algorithms and Procedural Systems

A major focus of the course is applying programming logic to creative problems.

Students explore algorithms such as:

K-Means clustering
Procedural pattern generation
Data-driven systems
Automated workflows

One project involves creating an embroidery system using image input and clustering algorithms.

VEX for Motion Design and Dynamic Constraints

The course also applies VEX to motion design workflows.

Students learn how to:

Generate procedural connections
Create dynamic constraint systems
Control Vellum simulations
Build reusable procedural setups

These techniques are useful for creating complex motion graphics and FX-driven animations.

Create Procedural Knit and Fabric Systems

The final projects focus on advanced procedural pattern generation.

Students build:

Knit patterns
Crochet-style structures
UV-based procedural systems
Point-pair intersection workflows

These projects demonstrate how VEX can be used to create highly detailed procedural assets.

Karma and Solaris Rendering Workflow

The course concludes with rendering and scene preparation.

Students learn how to use VEX-generated assets with Houdini’s modern rendering pipeline, including:

Solaris
Karma rendering
Procedural shading workflows
Final scene presentation

This connects procedural coding techniques with production-ready visual results.

Course Structure

According to Rebelway, the course includes:

30+ hours of training
8-week duration
Intermediate skill level
Online learning platform
Industry-focused projects

The instructor is Aaron Smith, a Senior Houdini TD with experience in VFX, 3D generalist workflows, and concept design.
